ZY-1型破片质量自动分析仪论证研究与工程制造。
The ZY-3 is the civil high-resolution optical stereoscopic mapping satellite independently developed by China. It is mainly used for 1 : 50,000 scale topographic mapping. One of the distin...
The ZY-3 is the civil high-resolution optical stereoscopic mapping satellite independently developed by China. The ZY-3 constellation of the twin satellites operates in a sun-synchronous, near-polar, ...
According to the function, land space types are divided into key development areas, restricted development areas and forbidden development areas in Sichuan Province. This paper monitors and analyses t...
Sugarcane is one of the most important crops in Guangxi, China. As the development of satellite remote sensing technology, more remotely sensed images can be used for monitoring sugarcane crop. With t...
Remote sensing optical image cloud detection is one of the most important problems in remote sensing data processing. Aiming at the information loss caused by cloud cover, a cloud detection method bas...
The Ziyuan-3 (ZY-3) satellite, as the first civilian high resolution surveying and mapping satellite in China, has a very important role in national 1 : 50,000 stereo mapping project. High...
关于Györy-Sárközy-Stewart猜想     最大素因子  Gyö    ry-Sá  rkö    zy-Stewart猜想       2018/2/6
本文在一定条件下证明了, 当$a,~b,~c$ 均为正整数, 并且$a\geq b>c$ 时, 乘积$(ab+1)(ac+1)(bc+1)$ 的最大素因子大于$k\log\log a$,其中$k$ 为一个正常数. 特别地, 当$c
ZY-3 is the first civilian high resolution stereo mapping satellite, which has been launched on 9th, Jan, 2012. The aim of ZY-3 satellite is to obtain high resolution stereo images and support the 1:5...
This paper evaluates the stereoscopic capacities of the Chinese sensor ZiYuan-3 (ZY-3) for the generation of photogrammetric products. The satellite was launched on January 9, 2012 and carries three h...
The Chinese satellites HJ-1 A/B, CBERS-02C and ZY-3 have been recently launched and are considered as the main space platforms on orbit to acquire optical images for monitoring the Earth for various a...
DSM generation using stereo satellites is an important topic for many applications. China has launched the three line ZY-3 stereo mapping satellite last year. This paper evaluates the ZY-3 performance...
ZiYuan-3 (ZY-3) mapping satellite is the first civilian high-resolution stereo mapping satellite of China. The satellite’s objective is oriented towards plotting 1:50,000 and 1:25,000 topographic ma...
ZY-3 is the first Chinese civilian high-resolution stereo mapping satellite. ZY-3 is equipped with three-line scanners (nadir, backward and forward views with 2.5 m and 4.0 m resolutions, respectively...
为明确抗戊唑醇草莓枯萎病菌 Fusarium oxysporum f.sp. fragariae 突变体ZY-W的生理生化特性,分析其抗性风险及可能的抗性机制,比较了对戊唑醇抗性达34.2倍的ZY-W和敏感菌株ZY在苯丙氨酸解氨酶(PAL)及过氧化物酶(POD)活力、对渗透压的敏感性、相对渗率、可溶性蛋白含量及酯酶同工酶图谱等方面的差异。结果表明:ZY-W突变菌株体内的POD和PAL活力均高于ZY...
